Question

What are the twin-primes? Write all pairs of twin-primes between 50 and 100.

Answer 1

Twin primes: Two prime numbers are said to be twin primes if there is only one composite number between them.
For example, (3, 5) and (5, 7) are twin primes.

Twin primes between 50 and 100 are (59, 61) and (71, 73).
